Tire tread



FIG. 1 is a perspective view of a tire tread showing our new design, it being understood that the tread pattern repeats circumferentially throughout the outer circumference and shoulder of a tire, the opposite side perspective view being identical thereto; and,

FIG. 2 is a front elevation view thereof.

In the drawings, the dark stippled surface shading represents the side surfaces of the tread blocks and the medium dark stipple surface shading represents the recessed groove portions of the tire tread having a depth as best illustrated along the right edge of FIG. 1.

The broken lines depict environmental subject matter only and form no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
